Pippa Middleton and James Matthews are on a mission to rack up as many frequent flier miles as possible during their honeymoon, or so it would appear.

The two were spotted once again boarding a plane in Australia, this time to jet off to Darwin, the capital of Australia's Northern Territory.

As the Daily Mail noted, the sister of the Duchess of Cambridge arrived in Darwin wearing a sleek white blouse by Orla Kiely, huge oversized sunglasses, her favorite Castaner espadrilles and carrying a $260 handwoven straw tote by Sensistudio.

Matthews and Middleton didn’t stay on solid ground for very long: Upon arrival in Darwin Matthews and Middleton quickly boarded a small charter plane, which could be taking them to one of the few luxury retreats in the region with their own airstrips, News.com.au reported.

Perhaps Middleton and Matthews added the destination to their world tour of a honeymoon at the recommendation of Will and Kate, who visited Uluru in April 2014.

Darwin is just the latest stop on what could be the most fabulous honeymoon in history. Prior to the stop in Darwin, the duo spent 36 hours in Sydney, Australia, where they stayed at the luxurious Park Hyatt Sydney, which offers visitors a heated rooftop pool, spectacular harbor views and even a private butler.

And before Sydney, the pair spent a few days on the Pacific island of Tetiaroa, where they stayed in the glamorous retreat known as The Brando, which offers private huts, an eco-friendly spa and plenty of adventure for the thrill-seeking newlyweds.
